To make get paint blank and white are mixed in the ratio 5:3.. How much black paint needed for
A) 10 litres
B) 12 litres
C) 21 litres i have got as far as in total there are 8 parts.... help please
10litres divided by 8 parts which mean 1 part is worth 1.25l (10/8=1.25)
Therefore you need 5x1.25 of the first colour, and 3x1.25 of the second.
Repeat this for all amounts starting with dividing the parts by the amount of paint you need.
So for 6 would be 8 dividee by 6 = 0.75 1part = 0.75 then 0.75 x 5 whixh is 3.75?
For part a) you would do (5/8)*10
